-IMPROVEMENT IN STEAM AND WATER COCKS.

Specification forming part of Letters Patent No. 92,622, dated July 3,1877; application filed May 5, 1877.

To all whom it may concern:

Be it known that we, Aueusrus GUILD and BRAINARD S. Lnwrs, ofMiddletown, in the county of Middlesex and State of Connecticut, haveinvented a new and valuable Improvement in Steam and Water Cocks; and Wedo hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a longitudinal centralsection of my improved cock; and Fig. 2 is a cross-sectional viewthereof.

Thisinvention has relation to improvements in straightway steam andwaste cocks; and it consists in combining with a barrel or casing,having tapering interior Walls and opposite inlet and outlet aperturesin line with each other and eccentric to the axis of said barrel, of atapering plug, conforming to the taper of the barrel, having a water-wayextending through it adapted to register with the said apertures, andprovided with an axial stein carrying a hand-wheel or handle thatextends through a rabbeted screw-cap applied to the open end of thebarrel-that is, adjustable relative to said barrel and is provided witha wrench-seat for facilitating said adjustment and taking up the wear,all as hereinafter more fully set forth.

In the annexed drawings, the letter A designates a metallic barrel for asteam or water cock, that is open at one end, and provided upon its openedge with an inside screwthreaded portion, b. it also has in its sides,opposite to each other, a screW-threadedinlet and outlet, lettered B B,that are eccentric to the axis of the barrel. The latter has taperinginside walls a a, the form of its hollow being a frustum of a cone. 0represents a metallic plug having a form to fit snugly in the barrel,and provided with a water-way, c, bounded at its upper and lower ends bydisks d d, the first of which rests snugly upon the bottom of thebarrel. The plug 0 has an axial stem, D, of suitable length, upon theend of which an operating handle or wheel, E, is applied. This stemextends through and has its hearings in a metallic cap-plate of the samediameter as the larger end of the barrel. The plate F has upon one ofits faces a screwthreaded rabbet, k, that engages the threaded part a ofthe barrel, and upon its remaining face a prismatic wrench-seat, G, bymeans of which the cap is conveniently applied to the barrel. The stemaforesaid extends through the wrench-seat Gr centrally, and it is thusafforded a more extended and durable bearing. When the cap-plate isforcibly set up its under side will come in forcible contact with theend of the plug before its flange 11, formed by the rabbet it, reachesthe edge of the barrel. By this means, as the plug is worn away by longuse upon its sides and ends and a leak occurs, the lost motion may betaken up by simply applying a wrench to the wrenchseat and giving thecap-plate a slight turn. By this meansrgmi ab e to dispense with all andevery packing applia ees. a-

My improved cock isapplicable to steam and water pipes, to steam-coilsfor heating purposes, and to any and all devices, wherein suchappliances are customary or useful.

What we claim as new, and desire to secure by Letters Patent, is-- In awater or steam cock, the combination with the barrel A, having a conicalhollow, and inlet and outlet B B5, upon one side'of the center of thecase, of the tapering plug 0, having end disks d 61, forming awater-way, 0, the rabbeted screw-cap F, having the wrenchseat G, and astem extending through said cap and seat, substantially as specified.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
